The efficiency of film cooling will be increased with the increase in blow ratio, and it has a highest value in the direction of flow.

冷却效率随吹风比的增加而增大， 且沿气流方向冷却效率存在一极大值；

Under the constant blow ratio, the higher the mainstream velocity is, the higher the average effectiveness and average heat transfer coefficient are.

同一吹风比下，主流速度较高的，平均效率及平均换热系数也较高。

If this were in line with the Basel rules it would take the total ratio to 13.5%, easily enough to have dealt with the losses of Britain's worst blow-up, HBOS.

如果这项规定要跟巴塞尔协定挂钩的话，总比率会达到13.5%，这样很容易的就可以帮助英国哈利法克斯苏格兰银行挽回损失。
